Outlet serves as fail-safe

Ground fault circuit interrupters (GFCIs) are designed to protect people from electrical shock and electrocution. A GFCI constantly monitors electricity flowing in a circuit. If it senses any loss of current, it quickly switches off power to that circuit.

GFCIs can be installed at the main service panel or in place of ordinary outlets. Typically, GFCIs are installed in areas where water and electricity mix in close proximity, such as a bathroom, garage, kitchen or basement.

GFCIs can be damaged or wear out due to voltage surges from lightning, utility switching or normal use. Just because an outlet works does not mean that the GFCI is functioning. GFCIs should be tested monthly to ensure they are in working condition.

Whether you have a receptacle-type or circuit breaker-type GFCI, pushing the "test" button should turn off the power of the circuit. Portable GFCIs should be tested before every use. Simply press the "reset" button.

Smoke alarms

On average, eight people die in a home fire each day in the U.S., for a total of nearly 3,000 fatalities every year. Roughly two-thirds of these deaths occur in homes without working smoke alarms. Smoke alarms save lives by providing early warning of fire. Newer smoke alarm recommendations and technologies provide greater levels of protection than ever before.

Smoke alarms should be installed in every bedroom, outside each sleeping area and on every level of the home.

Test smoke alarms monthly by pushing the "test" button or using other procedures recommended by the manufacturer. Smoke alarm batteries should be changed at least once a year. If an alarm "chirps" or "beeps" to indicate low batteries, change them right away. Replace all smoke alarms at least every 10 years.

Arc fault circuit interrupters

Arc fault circuit interrupters (AFCIs) replace standard circuit breakers in your home's electrical service panel. AFCIs provide a higher level of electrical fire protection, detecting hazardous arcing conditions traditional breakers were not designed to recognize, and shutting down the electricity before a fire can start.

AFCIs can stop working without showing signs of failure. Test AFCIs after installation and once a month to make sure they are working properly.

To test: Push the "test" button. The breaker handle should go to the middle or off position.

To reset: Move the breaker handle to the off position and then to the on position.
